Opkg downgrade

Like most Linux distributions or mobile device operating systems like say Android or iOSthe functionality of the system can be upgraded rather significantly by downloading and installing pre-made packages from package repositories local or on the Internet.

The opkg utility is the lightweight package manager used for this job. Opkg is a fork of ipkgthe package manager used in NSLU2's Optwarewhich is designed to add software to stock firmware of embedded devices.

Opkg is a full package manager for the root file system, including kernel modules and drivers, while ipkg is just a way to add software to a separate directory e. Opkg is sometimes called Entwareas it is used also in the Entware repository for embedded devices a fork of OpenWrt community packages repository.

The package manager opkg attempts to resolve dependencies with packages in the repositories - if this fails, it will report an error and abort the installation of that package. Missing dependencies with third-party packages are probably available from the source of the package. To ignore dependency errors, pass the --force-depends flag. For such usage of OpenWrt firmware, it's warmly recommended to use the Image Builder to make a flashable image containing all packages you need.

You can use glob patterns. The Description can contain line breaks, so using merely grep is inapt since grep is line-based. Note1: The size is the size of the gzip compressed tar archive. At installation package gets un-tared and decompressed, but then again JFFS2 uses compression itself. Note2: Since the compression of JFFS2 is transparent, commands like ls will always report the size of the uncompressed file. To install a package run the following commands. List of available packages is lost upon reboot, so make sure to update the list before trying to install a package.

You can make use of glob pattern s directly and also write a little shell script to use Regular expression s and otherwise further process information. Use a pipe and grep or awk or sed to filter that output:.

Exceeding the flash space or failing to download all needed upgrades might brick the router. As you can see, it sets default folders.

There should however be a way to specify the desired version on the command line. I'm not sure if there is one, I'll have to investigate. Original comment by paul.

The usage page says: "--force-downgrade Allow opkg to downgrade packages" From this description, I would expect that using "--force-downgrade" as an option on the install command would let me install an older version of a package when a newer version of the same package is already installed. I cannot get this to work. Success 2 Install the r Success 3 Build a new local opkg repository containing both the r Success 4 Install the r Repeat step 1.

Success 6 Try downgrading from r No matter what I try, I cannot install r The reason that I care about this is that I am trying to automate a potential downgrade of an embedded system and I would rather not be concerned with removing whatever package is currently installed.Has anyone been able to get the opkg --force-downgrade option to work?

The only way I can revert a package to a previous version is by uninstalling it, restricting access to the only the specific version I want either by removing the package from the repo or directing the sbRIO to another repo that doesn't have the updated versionand reinstalling the package.

I'm hoping somebody has a better way. I was hoping to find a way to retrieve the prior package from the repository and downgrade it all in one step, much like an upgrade works. This adds more complexity when trying to automate the process. Usually, the feeds put up by NI only have one version of a particular software package, so there's usually nothing to downgrade to. Could you share your use-case where you're interested in automating downgrading software packages?

You can check which version you are running via "opkg --version", if it is 0. If not, you may want to consider upgrading.

We're running into some problems getting a newer version installed on our Maybe because I'm not using any options? Can you create a list of steps expalining how to compile and deploy it to an sbrio?
